Move to Dropbox

I was informed the yesterday that my files were not working on Minus. I think they have disabled the download of anything that is not Text, Picture, or Audio. Since this is the case, I have moved all of my files, and a few extras, to Dropbox.

This is the new link: https://www.dropbox.com/sh/3ttzt76u70t578c/23V8V2s7is

Hopefully they will be of benefit to someone.

PuTTY, ST_MEM, and Arduino

While I still have not made as much headway as I would have liked to, I am slowly inching towards my original goal.

I have made a decent discovery. As I posted earlier when I try to flash the new firmware onto my hard drive with ST_MEM_SDLD, the flashing usually succeeds, but the but the drive refuses to see that APP code, and I am stuck in Level F. I Recently discovered, however that if I switch back and forth between PuTTY and ST_MEM, it works about 90% of the time. At first, I set the speed, and send the initial preparatory flashing command via PuTTY, then disconnect that terminal and switch to ST_MEM for the actual flashing procedure. (PuTTY doesn’t have the necessary code for the SDLD protocol. If I could find some documentation on this protocol, I would try to put it in myself.)

As it stands, the APP Code flashes successfully most of the time, and I am able to get to Level T, but as yet I still have not been able to get the CERT Code to flash correctly. I’m not sure what I am doing wrong. I keep working, though in hopes that someday soon, it’s secrets will be made know to me. We are making progress!

I have also discovered that by using an Arduino in place of my TTY/R233 adapter, I have gotten a more reliable connection. This has resulted in fewer failed flash attempts. (Prior to using this, sending the APP code would freeze half way through, and I would have to start over about 65% 0f the time)

To set up an Arduino to do this, just put a jumper wire from the Reset Pin to GND. Then your computer will detect the Arduino as a COM port. You can then hook up your hard drive to the Tx and Rx pins on the Arduino.

Mild Success

I think alot of you have been thinking that I have forgotten this project, or have given up. This is definitely not the case. I have not really had much to report lately, but I have had a few mild, yet incomplete successes in restoring my hard drive to working condition.

With the help of Vorian, who commented on my very first post, I have been able to get a firmware that was made for my drive. I also was able to flash the first parts of the app code to the drive, and was also once able to again access the T> prompt of the drive. Unfortunately for me it would seem that st_mem_sdld is quite buggy, and very unpredictable in it’s results. Since this is the case, I am still stuck with a bricked drive. I am in the process of trying to find another/better way of sending the app code, cert code, and cert tables to the drive.

As you can see, the process, when it decides to work, can work. I am still very hopeful for what the future might bring, and look forward to finishing this hack.

When I do finally figure out the best solution, I will create another post with full details of the process. If any of you have any suggestions, I am as always open, and will try my best to respond to every comment I get.

Thanks again to Vorian for all the help he has given me over the past few weeks.
